In a warp knitting machine, several beams are pivotally supported by a single shaft and rotated simultaneously to send out warp threads.

様に各ビーム毎に異なる経糸の張力の不揃いは編
目不良の直接の原因となる。 Therefore, even if the length of the warp wound on each beam is the same, if the outside diameter of the wound beams is different, the warp sent out from the beam with the larger outside diameter will become slack, and on the other hand, The warp yarns that are sent out from the beam with a narrow outer diameter are under tension. In this way, uneven warp tensions, which differ for each beam, are a direct cause of stitch defects.

意の長さの部分毎に要求される。 In other words, each beam set on a warp knitting machine must be made uniform not only in the amount of winding (thread length) but also in the diameter of the beam, and the uniformity depends on the total length of the warp wound on the beam. is required for each part in , that is, for each part of arbitrary length.

Regarding the standard diameter D of the beam B corresponding to each cumulative length L, the ratio calculated by the comparison judgment element dD exceeds the limit of the standard ratio set in the reference value storage element LD, and the beam If it is determined that the diameter of
The tension compensator C is driven from the comparison/judgment element dD to the tension control device TC via the mediating lever LB to adjust the tension. F is the beam body flange.
従つて、従来のビーム巻取装置BAによると、
順次巻き上げられる数本のビームそれぞれの経糸
の各累計長さ毎のビームの直径は、全ビームにわ
たつて一定に揃えられることになつている。 Therefore, according to the conventional beam winding device BA:
The diameters of the beams for each cumulative length of the warp yarns of several beams that are wound up in sequence are supposed to be uniform over all the beams.
従来のビーム巻取装置によると、経糸がマルチ
フイラメント糸の場合には、順次巻き上げられる
数本のビームそれぞれの任意の累計長さにおける
ビームの直径が略同一に揃えられるが、経糸が紡

According to conventional beam winding devices, when the warp is a multifilament yarn, the diameters of the beams at any cumulative length of several beams that are sequentially wound up are approximately the same, but when the warp is a spun yarn, In some cases, the stitches are not evenly aligned, causing stitch defects.

計算値ｄは実測値に極く近似したものとなる。
After intensive research into this problem, we found that since multifilament yarn consists of many thin filament yarns, yarn breakage does not occur even if it is not twisted. It is only lightly twisted, and when it is rolled up by a beam, it spreads out like a flat tape and wraps around it.Therefore, as shown in Figure 7, there are no gaps between adjacent multifilament threads, and it is difficult to wind the film around. The outer peripheral surface of the beam becomes smooth.
Therefore, the calculated value d of the beam diameter calculated by the diameter conversion element Bd by the computer CPU based on the signals from the rotational speed conversion element NE and the speed conversion element VMS becomes very close to the actual measurement value.

必ずしも一致しない。 On the other hand, since spun yarn becomes short staple fibers, it cannot be formed into a yarn without twisting, and due to the twisting, the cross section of the spun yarn does not spread out into a tape shape even when wound onto a beam, but is circular. , and the arrangement gap maintained between the adjacent spun yarns in the process from the guide roller GR to the beam B is maintained as it is on the outer peripheral surface of the beam, so that the outer peripheral surface of the beam is maintained as shown in FIG. The warp threads are wound one after another on the
Y 1 , Y 2 , Y 3 , Y 4 ... are overlapped directly above the previously wrapped spun yarn (convex portion), or are gaps between the previously wrapped spun yarn (convex portion) ( It creates unevenness by entering the concavity (concavity). Therefore, the computer CPU converts the diameter conversion element Bd based on the signals from the rotational speed conversion element NE and the speed conversion element VMS.
The calculated value d of the beam diameter calculated in 2 does not necessarily match the actually measured value.

良を惹起するものと推考された。 In this way, with the conventional beam winding device BA, based on the calculated value d of the beam diameter that does not match the actual measurement value,
In the comparison judgment element dD, the tension control device TC is driven by checking the standard diameter D of the beam B corresponding to the cumulative length L of the predetermined warp yarn Y set in the reference value storage element LD. In the case of spun yarn, the diameters of the beams at any given cumulative length of several beams that are wound one after another are not uniform, which is thought to cause stitch defects when they are placed in a warp knitting machine. .

Ｂの巻取太さ（直径）が管理される。 The rest is exactly the same as the conventional beam winding device BA, and the diameter d of the beam B corresponding to each cumulative length L of the warp Y calculated by the diameter variable conversion element Ld is set in the reference value storage element LD. The tension control device calculates the standard diameter D of the beam B corresponding to each cumulative length L of the warp yarns Y according to the ratio calculated by the comparison judgment element dD.

従つて経糸Ｙの累計巻取長さＬに比例して増加す

That is, the detection signal from the diameter detector DM is an actual measurement value that is mechanically averaged by the touch roller TR that is in sliding contact with the outer peripheral surface of the beam.

Since the device TC is operated, the control accuracy of the winding thickness (diameter) of the beam B based on the tension of the warp Y is improved, and even when the warp Y is a spun yarn, the cumulative winding length L of each of multiple beams can be adjusted. It is possible to wind the corresponding winding thickness (diameter) at a constant level, which eliminates stitch defects in warp knitting machines, and by using a conventional computer CPU, it is possible to simply use the Tatsuchi roller in the beam winding device BA. It is extremely practical because it can be implemented by partially modifying the TR and diameter detector DM.
